Grade 10 Up–This detailed volume "concentrates on civilizations that arose east of the Caspian Sea," from modern Afghanistan and the Aral Sea south to India and Sri Lanka and east to Japan, Korea, and the islands of Southeast Asia. The years covered range from 3000 B.C.E. through the 15th century. Entries vary in length from a paragraph to several pages, with the longer presentations followed by short lists for further reading; the appendix contains a comprehensive bibliography. Topics include dynasties, cultures, archaeological sites, artifacts, religions, temples, palaces, agricultural and economic development, trade, and individuals. The text, though dry, is thorough and up to date, incorporating descriptive material and, where relevant, the various interpretations of an item's or site's significance.
